'All night' in the Bible

It repenteth me that I have set up Saul to be king; for he is turned away from following me, and hath not fulfilled my words. And Samuel was much grieved; and he cried to Jehovah all night.

all the valiant men arose and went all night, and took the body of Saul and the bodies of his sons from the wall of Beth-shan, and came to Jabesh, and burned them there.
